This invention relates to yarn carriers having yarn wound thereon for subsequent use. 1

It is now the ordinary practiceflto pro Vide yarn carriers with arn by winding the yarn upon thecarrier, either by warp winds or filling winds. In warp wound yarn carf riers the yarn is wound upon the carrier in cylindrical layers, while in filling wound carriers the yarn is laid upon the" carriers in conical layers so that it may be withdrawn from the carrier lengthwise thereof. Fill ing Wound yarn carriers are now enerally employed in the spooler and as We t' in fil ling replenishing looms. When employed in the spooler, a lengthof yarn is withdrawn from the yarn carrier and tied or connected to rotating bobbins in the spooler. When employed as weft in a filling replenishing 100111, a lengthof yarn is similarly withdrawn from the end of the y'arncarrier and attached to a fixed point, While the wound carrier itself is mounted in a hopper for transfer to the shuttle on filling replenishment. In either of these" cases, slack is liable to occur in the yarn withdrawnfrom the carrier and cause snarls and kinks to be formed, which, in the case of the spooler,

may eventually vappear in the warp of the.

WOVGII cloth, and; in the case of theiilling replenishing loom; may be carried into the shed and appear as a defect in the cloth. Furthermore, when used as weft in afilling replenishing 100m the withdrawal of the yarn from the end conical layer of the car'- rier is liable to disturhthecomfe'el winds and such winds" ma become displaced or slough, causing entanglement and b eakage of yarn either at the time of transfer or during the passage of the shuttel through the shed.

One of the objects of the present invention, therefore, is to rovide a yarn; carrier so wound with yarnthatiio slack will occur in the yarn in tying in the spooler or tying the end to a fixe part in replenishing looms, to the end that kinks and snarlswill be prevented, and in case of use in a filling replenishing loom, sloughing or displacement of yarn in the onical layer at the tip ,end portion of the carrier cannot occur. In accordance with the present invention, the yarn carrier is wound with yarn conical la ers of filling wind, so that the yarn may e readilyfwithdrawn endwise of the yarn car'rier durin subsequent use, and to provid a length of arn fortying", either in the spool'ei or'a til ing replenishing loom, without uslng the filling wound portion of the terrier, the filling wound yarn on the carrier is overla'idflb-g an ddditional windcf the same yarn, eit er' of filli-n or Warp graduation, and preferably of the same traverse as the easiest layers. The length oflyarn in the overlying additional or spe cia' wintlslio'ul d be suflicient to enable the yarnen-d to be tied up in thefspooler or secured tdwfixed point in the loom without withdrawing yarn from the end conical er tension in withdrawing-yarn from the overlying Winds, the yarn is maintained under suflicient stretch to prevent slack be tween the carrier and the secured end of the yarn. Under these conditions snarls and kinks inth'e yarn will hem-wanted; sloughin'gor' displacement of the endconical winds cannot occur, and perfect cloth will Woven, both-in warpand Weft.

' Asillusti'ative o the advantages of the present" lIlYIltlOll; it will be hereinafter descrihed asemployed in afill-ing' re lenishing loom,- although it is to be un erstood that the invention may be used in the spooler or other machine wherein yarn is withdrswmfrom the end of tl'ie yarn carrier.

ti U

tle, and, as shown by Fig. 1, the loom frame 1 has mounted thereon the hopper stand 2, supporting a rotary 110 per 3 in which are mounted aseries of filing carriers to be transferred to the shuttle, as usual. Extending laterally of the hopper is the stud or shaft 4 having an end securing member 5, and. on the stud or shaft 4 is mounted the disk 6. The lay 7 has the usual shuttle box 8 in which the shuttle to be replenished is positioned prior to transfer. These arts and the transferrin mechanism may be all as now common in filling replenishing looms and need no further description.

When the filling carriers 9 are to be placed in the hopper, a length of filling a is withdrawn from the filling carrier and attached to the securing member 5, and should the length of filling a be withdrawn from the end conical wind of the filling wound carrier, it is liable to produce a sloughing or displacement of the yarn at the end of the filling carrier and cause slack, with the production of snarls and kinks in the filling, so that when a filling carrier is transferred to the shuttle, suchsnarls and kinks are liable to be drawn into the shed and produce imperfect cloth, or breakage of am may occur.

11 accordance with the present invention, these objectionable defects are avoided by furnishing a length of yarn wound on the exterior portion of the filling winds, sufficient to permit the end of the yarn to be attached to the holder without the disturbance of the conical end layer of the fillin wind or production of slack in the yarn between the filling carrier in the hopper and the holder 5.

The filling carrier 10 is herein'shown as a bobbin, although any usual character of filling carrier may be emplo ed, and such filling carrier is provided wit a head portion 11 on which are the usual rin 12 for engagement with the bobbin holding jaws in the shuttle.

The filling carrier 10 has filling wound thereon in conical layers 13 substantially throughout the entire length of the yarn carrier, so that during weavlng the yarn may be withdrawn endwise from the carrier as the shuttle is picked. V In accordance with the presentinvention, a part of the cylindrical portion 14 ofthe filling wound carrier is overlaid with a series of winds 15 of the same yarn which forms the filling winds, and as it is expedient to complete the winding of the carrier in one operation, or in the same machine, the traverse of the winds 15 on the exterior portion of the filling wound carrier may be of substantially the same traverse as the conical winds of filling. That is to say, the distance traversed by the winds, as indicated at 16, is substantially the same as an element of the conical winds, as indicated at 17 with the result that sufficient yarn is laid upon the completed filling wound carrier to provide for withdrawal of the end of yarn, as indicated at 18, for its attachment or tying up, either in the spooler or filling replenishing loom, without at the same time disturbing any of the filling Winds.

The additional yarn 15 upon the exterior cylindrical portion of the filling wind may be laid upon the filling wind. in one or more layers, dependent uaon the length of yarn necessary to proper yeflect tying or securing the end without drawing upon the filling wound portion of the yarn, and, as shown by Figs. 2 and 3, these winds may extend from the base or step portion of the conical wind at the tip of the bobbin towards the head of the bobbin, although such position of the additional winds of yarn may be varied.

This possible variation in the position of the tying or additional winds, which in the present instanceare shown as of warp wind graduation, is indicated by Fig. 4, wherein a part of such additional Winds extends along the cylindrical barrel portion of the filling winds, as at 19, and laps over a portion of the base or step of the tip and filling wind, as at 20, to lock the filling wound yarn from sloughing or disturbance and, at the same time, provide a len th of yarn for securing the end thereof without withdrawing yarn from the conical filling winds. In the present illustration of the invention, the filling wound carrier is shown as having the additional length of yarn woundupon the filling in the close 'SplIfllS of warp wind as afiording an efficient bindin influence upon the filling windto prevent sloughin or displacement of the end conical win s either during handling or while in the 100111 hopper and to insure sufiicient tension in the withdrawal end, but the invention is not necessarily restricted in, this respect because the urpose thereof is to provide additional win 'ngs of yarn about the completely filled wound carrier of a length suflicient to enable the end of the yarn to be withdrawn under tension for attachment to a fixed part of the 100111 or tying upin the spooler without the productionof slack, snarls, kinks, or disturbing the conical filling winds.

Thus the present invention provides a yarn carrier having the yarn wound thereon in the conical layers of filling wind and the same yarn wound upon a part of the body or cylindrical portion of the filling wind to provide van additional or supplemental length of wound yarn for securing the end in a filhng replenishing loom and. permit the shuttle tobe picked after transfer without the production of slack and liability of kinks and sna rls that might be carried into the shed.
